ABSTRACT: To efficiently improve the security
of buildings against extreme accidents, the Architectural Society
of China organized a special committee to compile the Design
specification for the collapse prevention of buildings. Based on
the corresponding research in China and the relative design codes
in various countries, this specification recommends design and
analysis methods for the prevention of earthquake-induced collapse,
progressive collapse, fire-induced collapse, construction
error-induced collapse and so on. This paper provides a brief
summary of the framework of this specification and presents the
main innovative work in it, for example, the improved tie force
method, the progressive collapse resistance demand based on energy
method, the earthquake-induced collapse resistance evaluation based
on incremental dynamic analysis and the fire-induced collapse
prevention design calculations.
